Compared to those uninfected, infection groups reported at least a two-fold increase in fever, cough, loss of smell\/taste, and shortness of breath. Based on persistent new symptoms, PASC was identified in only 1.5% of participants with COVID-19.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Our study suggests lower than expected prevalence of PASC in MS and a complex association between infections and development of new persistent symptoms following infections.
